Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of umbilical morphology correction, specifically to an incision protection device for postoperative umbilical morphology correction. Background Technology
[0002] Single-port laparoscopic surgery involves making an incision at the umbilicus. Because the scar is concealed and the incision is small, it greatly satisfies patients' high requirements for aesthetics. In recent years, it has been widely used in gynecological and surgical procedures. However, postoperative umbilical morphology correction and incision management remain clinical challenges.
[0003] In existing technologies, umbilical incision suturing often uses swab packing or rigid tube compression devices for shape fixation. These methods have significant drawbacks, easily leading to scar misalignment and adhesion, and the closed design hinders tissue fluid drainage, increasing the risk of infection. Traditional incision protectors, due to the dense and concave skin around the umbilicus, often suffer from unstable fixation and insufficient compression, resulting in bleeding accumulation and delayed healing. Furthermore, existing devices generally lack sustained-release drug function, relying on frequent postoperative dressing changes, which not only increases patient suffering but may also damage newly formed tissue due to improper operation. Therefore, there is an urgent need to develop an umbilical incision protection device that combines shape correction, breathability and antibacterial properties, drug release, and dynamic monitoring functions to address the problems of insufficient shape maintenance, weak infection control, and long healing periods inherent in traditional techniques. Utility Model Content
[0004] The purpose of this invention is to provide a surgical incision protection device for postoperative umbilical morphology correction, in order to solve the core problems of traditional techniques, such as insufficient morphology maintenance, weak infection control, and long healing period.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a surgical incision protection device for postoperative umbilical morphology correction, comprising a device body and an observation window structure. The device body includes a drug layer, a support layer, and an antibacterial silicone layer. The drug layer is attached to the inner side of the support layer, and the antibacterial silicone layer is attached to the outer side of the drug layer. The observation window structure includes a rotatable turntable with a window fixed on it. An annular ring is fixed at the inner opening of the support layer. A snap-fit structure is provided on the observation window structure, and the snap-fit structure is detachably connected to the annular ring. A positioning structure is provided on the turntable.
[0006] In a further technical solution, the main body of the device has a mesh structure.
[0007] A further technical solution is that the antibacterial silicone layer has uniformly distributed pores.

[0010] In a further technical solution, the positioning structure includes an adhesive area fixed on the turntable, at least two adhesive areas are provided, and the two adhesive areas are symmetrically arranged relative to the window, and adhesive tape is adhered to the adhesive areas.
[0011] In a further technical solution, the observation window structure can be disassembled and replaced with a mounting plate, and the mounting plate is also provided with the buckle structure at both ends. The mounting plate is detachably connected to the annular ring through the buckle structure.
[0012] A further technical solution is provided with a pressing structure on the inner side of the mounting plate. The pressing structure includes an inflation tube and an air bladder.

[0025] like Figures 1-4 As shown, a surgical incision protection device for postoperative umbilical morphology correction includes a device body 100 and an observation window structure 200. The device body 100 includes three functional layers: a drug layer 102, a support layer 101, and an antibacterial silicone layer 103. The support layer 101 is located in the middle layer and is generally frustum-shaped, with one side of the frustum being open and the other side being curved. The support layer 101 has a mesh structure and is made of medical alloy material, such as one of nickel-titanium alloy, medical iron alloy, or medical copper alloy. The height of the support layer 101 is 1 to 5 cm, and the opening diameter is 1 to 3 cm. The specific size depends on the shape and contour of the patient's umbilicus. It can be 3D printed or woven from alloy wire. If the weaving process is used, a sealing edge should be set at the opening. The diameter of the alloy wire is 0.05 to 0.2 mm.
[0026] The drug layer 102 is attached to the inner side of the scaffold layer 101 and is a patch made of a drug and a sustained-release layer. The drug layer 102 also has small holes. The drug is one or more of the following: antibacterial and anti-infective drugs, analgesics, anti-inflammatory drugs, healing and repair drugs, and anti-scarring and anti-proliferative drugs. The sustained-release layer is one or more of the following: polylactic acid-glycolic acid copolymer, polycaprolactone, chitosan-based hydrogel, and hyaluronic acid nanofibers. The drug release adopts one or both of the following: a time-sequential release gradient and a responsive concentration gradient design.
[0027] The antibacterial silicone layer 103 is attached to the outside of the scaffold layer 101. The antibacterial silicone layer 103 is made of an antibacterial silicone material, such as silver ion antibacterial silicone, quaternary ammonium salt antibacterial silicone, natural extract antibacterial silicone, or a composite antibacterial silicone. The thickness of the antibacterial silicone layer 103 is 0.5 to 3 mm. The antibacterial silicone layer 103 has uniformly distributed pores to allow the drug to be released to the patient's navel skin. The outer surface of the scaffold layer 101 is coated with chitosan-based hydrogel. The amino and hydroxyl groups in the chitosan molecules can form hydrogen bonds, giving the hydrogel strong adhesion, which can better connect the outer antibacterial silicone layer 103.
[0028] In another embodiment, the scaffold layer 101 can generate a customized shape based on the 3D model of the patient's navel. The 3D model of the patient's navel is obtained by CT / MRI scanning and optical 3D scanner to obtain the anatomical structure data of the patient's navel. Based on the data, a customized device shape is generated to perfectly fit the anatomical structure of the patient's navel.
[0029] In one embodiment, the observation window structure 200 includes a rotatable turntable 201 with evenly distributed ventilation holes 204. A window 202 is fixed on the turntable 201. The observation window is made of polyurethane or polycarbonate and has a diameter of 1 to 3 centimeters. An annular ring 104 is fixed at the inner opening of the support layer 101. The observation window structure 200 is provided with a snap-fit structure 300, which is detachably connected to the annular ring 104. The turntable 201 has at least two deformation grooves 203, and in this embodiment there are two. The buckle structure 300 includes an elastic card 301. The elastic card 301 is elastic. One end of the elastic card 301 is fixed to the inner side of the turntable 201, and the other end extends outward through the deformation groove 203. A locking block 302 is fixed on the elastic card 301. The annular ring 104 is inserted into the locking block 302, so that the turntable 201 can rotate along the annular ring 104.
[0030] In one embodiment, the turntable 201 is provided with a positioning structure 400, which includes an adhesive area 402 fixed on the turntable 201. There are at least two adhesive areas 402, and in this embodiment, there are two adhesive areas 402, which are symmetrically arranged with respect to the window 202. An adhesive tape 401 is bonded to the adhesive area 402. The adhesive tape 401 can be medical tape. During operation, the medical tape is peeled off and then applied. Alternatively, it can be directly applied to the adhesive area 402 during production. If the adhesive tape 401 is directly applied during production, it needs to have an anti-adhesive layer. When using it, the anti-adhesive layer on the adhesive tape 401 is peeled off and then applied.
[0031] In one embodiment, the observation window structure 200 can be detached and replaced with a mounting plate 600. The mounting plate 600 is also provided with the buckle structure 300 at both ends. The mounting plate 600 is detachably connected to the annular ring 104 through the buckle structure 300. A pressing structure 500 is provided on the inner side of the mounting plate 600. The pressing structure 500 includes an inflation tube 501 and an airbag 502. The inflation tube 501 is fixed on the mounting plate 600 and communicates with the inflation device. The airbag 502 is fixed to one end of the inflation tube 501 and communicates with the inflation tube 501. After the airbag 502 is fully inflated, its outline is the same size as the inner outline of the support layer 101, so that the airbag 502 can press the drug layer 102 into the inner side of the support layer 101. The inflation device can be a hand-held inflation airbag or a manually inflatable air tube.
[0032] The method of using this incision protection device for postoperative umbilical morphology correction is as follows:
[0033] Medical staff first assemble the observation window structure 200 and the device body 100 together, manually pinch the two elastic cards 301, place the observation window structure 200 at the opening of the device body 100, then release the elastic cards 301 to make the ring 104 and the card block 302 engage, rotate the observation window structure 200 to adjust it so that the adhesive area 402 is as perpendicular as possible to the patient's incision. Then, insert the device body 100 with the opening facing outward into the patient's navel to complete the insertion action. Then, stick the adhesive tape 401 to the adhesive area 402 and then stick it to the patient's abdomen to fix the protective device. Subsequently, the internal condition of the device body 100 can be observed through the window 202. The rotating plate 201 can block some large particles from entering the device body 100.
[0034] If severe bleeding is observed, the protective device should be removed promptly, and the incision should be cleaned and treated.
[0035] If not, the internal drug layer 102 needs to be replaced periodically. The replacement method is as follows:
[0036] Medical staff pinch the elastic card 301 to disengage the card block 302 from the ring 104, then remove the observation window structure 200. Holding the main body 100 of the device with one hand, they use medical tweezers to peel off the drug layer 102. Compared to the traditional method of directly scattering gauze that is adhered to the patient's skin, this reduces the patient's pain. Then, a new drug layer 102 is taken and attached to the inside of the support layer 101. The mounting piece 600 is then installed. The inflation device inflates the air bladder 502 through the inflation tube 501, causing the air bladder 502 to expand and press the new drug layer 102 onto the support layer 101. The air bladder 502 is then removed. The compression structure 500 can be used directly for inflation and compression without the need for the mounting piece 600, simplifying the operation. After removing the compression structure 500, the observation window structure 200 is then installed.
[0037] The device forms a closed-loop treatment system with long-lasting antibacterial protection on the outer layer and precise drug release on the inner layer. It achieves the fixation of the surgical position and prevents adhesion of the surgical incision. The designed 204 vent facilitates air permeability and liquid leakage, reducing the risk of infection. The observation window allows for timely observation of the internal condition of the device. By rotating the locking turntable, the position of the tape can be adjusted to avoid the surgical incision.
[0038] Application examples of this device:
[0039] Example 1: Patient Wang, 28 years old, unmarried, underwent single-port laparoscopic myomectomy. She has a tendency to form keloids and has high requirements for the aesthetic appearance of the incision. This device was placed after the operation, with anti-scarring and anti-proliferative drugs placed in the inner layer. The umbilicus was natural after the operation, and no obvious scar formation was observed 3 months after the operation.
[0040] Example 2: Patient Li, 25 years old, 18 weeks pregnant, underwent single-port laparoscopic ovarian tumor resection.
